Description
Technical field
The utility model relates to a kind of auto parts and components, is specifically related to a kind of cylinder with filter screen of long service life.
Background technique
At present, the cylinder on the market enters to prevent dust by anti-dust seat is set in protecgulum, thereby prevents that dust from blocking exhaust port, causes cylinder deactivation, guarantees the working stability of cylinder.Yet, existing cylinder is only paid attention to the dustproof design of exhaust port, the suction port place is but without any dustproof or filter design, or such as the patent No. 200520124423.0 disclosed a kind of exhaust brake cylinder of diesel engines, although in the valve pocket of the outer end of valve seat, filter screen seat is installed, filter screen and filter screen packing ring, but but there is not stable fixation method, the design and installation of this filter screen packing ring is not firm, in use, inefficacy easily comes off, air is directly entered in the cylinder by suction port, simultaneously, be entrained in airborne impurity and also together enter in the cylinder, and impurity enter the wearing and tearing that can not meeting unavoidably cause piston and cylinder barrel, have a strong impact on the service behaviour of cylinder, reduced the working life of cylinder and be unfavorable for environmental protection.
The model utility content
The purpose of this utility model is to provide a kind of cylinder with filter screen, to solve that there is poor work stability in existing cylinder, working life is low and to be unfavorable for the technical problem of environmental protection.
For achieving the above object, the utility model provides a kind of cylinder with filter screen, comprise: protecgulum, bonnet, cylinder barrel, piston rod, piston, spool and protecgulum anti-dust seat, protecgulum, cylinder barrel are connected with bonnet and are connected, piston rod is arranged in protecgulum, part is arranged in the cylinder barrel, piston is arranged in the cylinder barrel and with piston rod and is connected, spool is arranged in the piston and with piston and is connected, the protecgulum anti-dust seat is arranged on inner the socket with piston rod of protecgulum and is connected, described cylinder also comprises a filter screen, and filter screen is arranged in the air intake passage of piston, and is connected with piston.
According to the described cylinder with filter screen of the utility model preferred embodiment, described cylinder also comprises a filter screen briquetting, after filter screen briquetting and filter screen are welded to connect, puts into piston, and evenly the riveting piston is fixedly connected with again.
Cylinder with filter screen of the present utility model improves existing cylinder, filter screen is installed at the place in the piston intake hole, the air that enters cylinder is filtered, thereby guarantee to enter the air cleaner in the cylinder, the device of having avoided causing because of the impurity of carrying secretly in the air weares and teares, guarantee the working stability of cylinder, greatly improved working life, and be beneficial to environmental protection.Simultaneously, in order to consolidate the installation of filter screen, also be provided with filter screen briquetting and filter screen and be welded to connect, put into again the even riveting piston of piston and be fixedly connected with, avoid filter screen to come off, further improved stability.Therefore, compared with prior art, the utlity model has working stability, long service life and be beneficial to the advantage of environmental protection.
Description of drawings
Fig. 1 is the structure sectional view that the utlity model has the cylinder of filter screen;
Fig. 2 is the schematic representation of the utility model filter screen;
Fig. 3 is the schematic representation of the utility model filter screen briquetting.
Embodiment
Below in conjunction with accompanying drawing, specify the utility model.
See also Fig. 1, Fig. 2 and Fig. 3, a kind of cylinder with filter screen, comprise: protecgulum 1, bonnet 2, cylinder barrel 3, piston rod 4, piston 5, spool 6, protecgulum anti-dust seat 7, filter screen 8 and filter screen briquetting 9, protecgulum 1, cylinder barrel 3 is connected with bonnet successively and is connected, piston rod 4 is arranged in protecgulum 1 part and is arranged in the cylinder barrel 3, piston 5 is arranged in the cylinder barrel 3 and with piston rod 4 and is connected, spool 6 parts are arranged in the piston 5 and with piston 5 and are connected, protecgulum anti-dust seat 7 is arranged on protecgulum 1 inner the socket with piston rod 4 and is connected, filter screen 8 is arranged in the air intake passage of piston 5 and with piston 5 and is connected, after filter screen briquetting 9 is welded to connect with filter screen 8, put into piston 5, evenly riveting piston 5 is fixedly connected with again.。
During the utility model work, air is entered in the cylinder by piston 5 by the suction port of bonnet 2, and when air passed through filter screen 8,8 pairs of air of filter screen filtered, and the impurity that mixes in the filtering air has guaranteed to enter the air cleaner in the cylinder.
Cylinder with filter screen of the present utility model improves existing cylinder, filter screen is installed at the place in the piston intake hole, the air that enters cylinder is filtered, thereby guarantee to enter the air cleaner in the cylinder, the device of having avoided causing because of the impurity of carrying secretly in the air weares and teares, guarantee the working stability of cylinder, greatly improved working life, and be beneficial to environmental protection.Simultaneously, in order to consolidate the installation of filter screen, also be provided with the filter screen briquetting, filter screen briquetting and filter screen are welded to connect, and put into the even riveting piston of piston again and are fixedly connected with, and avoid filter screen to come off, and have further improved stability.Therefore, compared with prior art, the utlity model has working stability, long service life and be beneficial to the advantage of environmental protection.
More than disclosed only be several specific embodiment of the present utility model, but the utility model is not limited thereto, the changes that any person skilled in the art can think of all should drop in the protection domain of the present utility model.
